The mid-infrared is of great interest for a huge range of applications such as medical and environment sensors, security, defense and astronomy. I will give a broad overview of the different activities recently launched in INL Lyon, in close collaboration with several French and Australian institutions, under the umbrella of “Mid-IR integrated photonics” with a particular focus on novel integrated...
The integration of a differential antenna in mainstream 65 nm CMOS was investigated. A 60 GHz prototype integrated circuit (IC) was developed, including a seal-ring and on-chip calibration structures. Measured results show excellent impedance matching properties over a 10 GHz bandwidth and a moderate antenna gain of −1.5 dBi. However, this is still a significant improvement as compared to state-of-the-art...
This paper presents an 8-elements phased array receiver front-end in 45nm CMOS technology. The receiver uses a 4-bit resolution RF phase shifter to compensate for the free-space propagation delay and an active eight-to-one power combiner enabling beam-forming. Each path shows more than 15.8dB of power gain with <0.5 dB of RMS gain variation for all 16 phase settings over the 3-dB gain bandwidth...
A complete ultra-wideband (UWB) radar system is presented in this paper. The radar system consists of UWB CMOS radar transceiver and two compact directional UWB antennas for the purpose of transmission and reception. Different possible applications were investigated in the domain of ranging and tracking using this system along with fast and efficient signal processing algorithms. The results obtained...
The integration of a CMOS power amplifier (PA) and antenna in printed circuit-board (PCB) technology is investigated. Both the PA and the antenna have a differential design to provide a reliable low-loss interconnect. A PCB package is proposed that enables the implementation of a high-efficiency antenna while providing mechanical rigidity. The interconnection between the PA and the antenna is realised...
